4" Radius Blocks

About This Item

Radius wood blocks for spot-leveling frets and fingerboards, just add sandpaper. Short length is great for working on compound radii. They make great fret-gluing cauls, too!

Create an accurate radius quickly and without guesswork.
We make these hardwood blocks for use with Stikit Abrasives, to radius a fretboard quickly, accurately and without guesswork.

Shaping fingerboards: use 80 through 220-gritLeveling frets: use 220 through 400-grit

When working on compound radius fretboards, simply change blocks as you progress along the neck.

These 4" blocks are used for spot leveling, and can also be used as a radiused clamping caul when gluing frets. The longer 8" blocks are better for consistent, full-fingerboard radius leveling.

Dimensions: 4" (101.60mm) long x 2-3/4" (69.85mm) wide

What's your radius?
Quickly find the curvature of a fingerboard or bridge with a set of radius gauges. Use them frequently to check your work as you smooth or shape a fingerboard or frets: a quick visual check keeps you from accidentally altering the shape—a mistake that's easy to make and hard to fix.

radius block

Excellent sanding block!

I didn't even shop around for where else I might have gotten a 16" radius sanding block (since StewMac always comes through for me, and FAST). But this was a VERY nice block, consistent. Did exactly what I needed it to do, and the price was pretty good. The project I used this on was an ESP Ltd B-255 that I converted to fretless (defretted, slot-filled w epoxy & rosewood dust, then covered the fingerboard with about 2mm of epoxy). Used this block to sand the epoxy on the fingerboard back to correct 16" radius. Worked Great!

Very good tool

Stewmac is very consistent with their products, this is the second block i bought, i have the 8" long one and i just wanted to get the shorter one to do a spot-radius correction near the heel of my fretless j-bass (approx. positions 15 - 20). Both blocks look just about perfect.
